8221,BLKCACHE_IOERR after creating snapshots. => fixed in svn/4.0.4,jptech,,"I get a BLKCACHE_IOERR after creating a 2nd snapshot on one of my VMs. It causes the VM to switch into suspended state when trying to boot the guest. Others have reported a similar problem here:
http://forums.virtualbox.org/viewtopic.php?f=6&t=38523
Some things that may be relevant:
* The VM was imported from an appliance that I created (VMDK disk)
* Everything works ok if I enable '''Use host I/O cache''' on my VM
* I'm using an AHCI SATA controller in my VM.
I experience this problem by doing the following:
* create a minimal guest installation
* export the guest as an appliance
* import the appliance as a new VM
* work on guest
* stop guest
* snapshot 1
* start guest
* work on guest
* stop guest
* snapshot 2
* error starting guest
